When you try to activate a Microsoft Office 2007 suite or Microsoft Office 2003, you may
receive an error message that is similar to the following:

Your installation cannot be activated because you have activated
up to the limit for your Product Key. For details about the maximum allowed
number of product activations, close this wizard and review the End User
License Agreement, available through the Help menu of this
application.

If you believe that you are getting this message in
error, click Back and choose the telephone option. The
telephone activation system will provide you the opportunity to speak with a
support representative about all activation issues.

This behavior may occur if you installed an Original
Equipment Manufacturer's (OEM) copy of Office, and you already installed
and activated the same OEM copy on another computer. OEM copies of Office 2007 or Office 2003 can only be activated on a single computer.

Note You can remove and then reinstall Office by using the same
product key on one computer successfully.
